BlackBox Component Builder is an IDE for Component Pascal programming language. BlackBox consists of modules, compiler and environment for their work over OS. It is also providing facilities for interface design and modules extension. Component Pascal is strongly typed and module based. The compiler is very fast. Each module is a unit of compilation and execution. Modules are brought into memory when specified. There is no need for 'headers'. Symbol files are automatically generated by the compiler for exported items. Data structures are automatically garbage collected when no longer referenced. The framework comes with a complete set of documentation for each module.
